Parallel Computing benchmarks

I've been doing some benchmarking and hope to post some results soon. I have some simple, easily-parallelized code that I've been trying different computing architectures on. These include:

• Single threaded java
• Single threaded C
• Multithreaded java
• Multithreaded C
• Vectorized C using x64 SSE Instructions
• Multi-core computing on an NVIDIA GPU with CUDA

It's been an interesting experiment and hopefully I can post results soon.
